To all it may concern:

Be it known that I, MILTON F. VVILLIAMS, a citizen of the United States, residing at St.

Louis, Missouri, have invented a certain new and useful Improvement in Cages for Crushers and Pulveriaers, of which the following is a full, clear, and exact description, such as improvement in cages forcrushers and pulver1zcrs, the Objfit being to construct a sectional cage so that the parts the eof will occupy a small amount of space in slapping and also to provide ring-mounts of varying sizes for the cage-bars whereby the several sections may be removed, new ring mounts of a diflerent size inserted so as to adjust the cage bars inwardly toward the axis of rotation of the revolving heaters to take up the wear on the ends of said heaters.

lo the drawings,'1 indicates the side frame of the machine, in which is mounted a rotatable shaft 2, having hammer or heater supports 3, pivotally carrying heaters l.

5 is the top or cover of the machine. 'Ilhe material to he acted upon is fed into a hopper at the forward end of the machine, at the lower end of which it is acted upon by the revolving heaters. The material is caused to pass over a cage onscreen until it is reduced to such size that its particles can pass through the openings therebetween, said screen pref-- erahly consisting of bars, as indicated. in the drawings. The side frames 1 are provided with curved seats 1 for receiving the cage bars and ring-mounts of different sizes, and in order to remove the cage and adjust it or put in new bars it is only necessaryto raise the hinged cover and withdraw the cage from its circular grooved seat.

It is part of my present invention to group the cagabars so that the cage may he inserted or removed in sections, and thus avoid binding or cramping, which is usually incident to the removal or insertion of a built-up cage. The bars 6 are preferably of uniform size throughout their length, and a number of these bars may be secured together by rivets 7, passing through the reduced ends thereof,

said bars being spaced apart by washers S of the desired thickness, so that a number of bars may constitute a cage unit. The curved seat 1. 111 the side frame 1 is of such radial depth as to receive the groups of cagedtwars 6 5 and leave a space within the circle of cagebars or outside them, depending u on the position it is desired that the cage shal occupy with respect to the path of rotation of the heaters. When the heaters are new and unworn, it is desirable that the cagedosrs rest against the outer edge of the groove 1, or that edge of the groove which is farthest from the axis of rotation of'thc heaters, and in order to hold the cage-bars or groups of cagebars in position I introduce a ring-mount 9, which iills the space between the cage'bars and the inner edge of the groove 1, or that edge of the groove which is nearest to the This is shown 211115 of rotation oi the heaters. in Fig. 2. I

' To adjust the cagehars inwardly when the hammers are worn, the ring 9 is removed and a ring 10 is em )loyed on the out-er side of the ca e-hars as s lOWIl in l l a an inner rin fl 9, of less depth than the ring Q heing employed to hold the cage-bars firmly in place. The shouldcrson the cagc hars are useful in holding these inner and outer ring mounts against lateral displacement. adjustment (shown in Fig. 4) an outer ring 10 of greater depth than the ring 10, is used and an inner ring 9", oitless depth than the ring 9, is used, the adjustments being cliented by dil'lterent-sized inner and outer rings, as 9 shown in Figs. 5, t}, and '7, the last-nlentioncd figure showing the use of an on tor-ring mount only, no inner ring being employed.

rom the above it will be seen that in. the

outermost position an inner-ring mount only ice but the combined depths of the inner and outer ring mounts must in every instance For the next o ends equal the depth of either the inner or the outer ring mounts. 7.) It will also be observed that the bars themselves are provided with restricted portions which serve to hold the ring-mounts in position,the shoulders adjacent the restricted portions serving to hold the ring-mounts against lateral displacement, and, further, that as the radii of the cage-bars change from the outermost to the innermost adjusted po sitions the groups of bars readily lend then1- selves to such a change. The purpose of riveting a plurality of these bars together is to facilitate and quicken the time in eifectin a change in the adjustment of the radial istance of the cage from the axes of rotation of the hammers but it is obvious that instead of grouping a plurality of cage-bars together the bars can be separately introduced.

Having thus described my invention, What i. claim as new, and desire to secure by Let- Patent, is-

l. The combination with a support having a curved groove, of cage-bars having reduced rejecting into said groove whereby shoul ers are provided on the cage-bars adjacent said grooves, a ring-mount cooperating with said shoulders, and means independent of said ring-mount for holding the cage-bars spaced apart; substantially as described.

2. The combination with a support havin a curved groove, of cage-bars having reduce ends rejecting into said groove whereby shoul ers are provided on the cage-bars adjacent said grooves, an inner-ring mount cooperating with said shoulders, and means independent of said ring-mount for holding the sags-bars spaced. apart; substantially as described.

(Shown in Figs. 2 andeiaete 3. The combination with a support havin no a curved groove, of cage-oars hav ng reduce ends Io ecting into said groove whereby shoul ers are provided on the cage-bars adjacent said ooves, an outer-ring mount cooperating with said shoulders, and means independent of said ring-mount for holding the cage-bars spaced apart; substantially as described.

4. The combination with a support having a curved groove, of cage-bars having reduce 5o ends pro3e'cting into said groove whereby shoulders are provided on the cage-bars adjacent said grooves, inner and outer rin mounts cooperating with said shoulders, an means independent of said rings for holding the bars spaced apart; substantially as described.

5. The combination with a sup ort liar in a curved groove, of cage-bars W 'eh extend into said groove, a ring-mount cooperating with said cage-bars, and fastening projecting through the ends of said sag. to secure a plurality of them together so as to form cage units; substantially as described.

6. The combination with a sup ort havin .6 5 a curved groove, of cage-bars w ch extend into said groove, andmeans separate from the cage-bars and adapted to be inserted in said groove for changing the radial distances of said cage-bars from'the center of the support; substantially as described;

In testimony whereof I hereunto sfiix my signature, in' the presence of two witnesses, this 10th day of Januar 19-05.
